For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention may be understood according to specific circumstances. In addition, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0026] The following Figures 1-6 describes a vehicle control device, a vehicle and a vehicle control method provided by the present invention.

[0027] Figure 1 is one of the structural schematic diagrams of the vehicle control device provided by the present invention. As Figure 1 shown, the vehicle control device includes an in-vehicle terminal (Telematics BOX, TBOX) 101, an in-vehicle gateway (Gateway, GW) 102, a vehicle control unit (Vehicle Control Unit, VCU) 103, and a battery pack management system (Battery Management System, BMS) 104.

[0028] Among them, the in-vehicle terminal 101 is connected to the vehicle control unit 103 through the in-vehicle gateway 102; the vehicle control unit 103 is connected to the battery pack management system 104.

[0029] The in-vehicle terminal 101 is configured to determine a charging state change message according to a charging state change instruction and output the charging state change message.

[0030] The vehicle control unit 103 is configured to change the vehicle charging state according to the charging state change message, determine a charging state message, and output the charging state message.

[0031] The battery pack management system 104 is used to perform a charging operation according to a charging status message.

[0032] The charging status change instruction is remotely sent by the back-end management platform (Telematics Service Platform, TSP) to the in-vehicle terminal 101 when it detects that the vehicle service has expired (such as the service contract has expired or the prepaid usage fee has been exhausted, etc.) or the vehicle service has been renewed (such as a new service contract has been signed or the usage fee has been prepaid again, etc.).

[0033] When the back-end management platform detects that the vehicle service has expired, the charging status change instruction sent is a charging lock instruction, that is, an instruction to restrict vehicle charging.

[0034] When the back-end management platform detects that the vehicle service has been renewed, the charging status change instruction sent is an unlocking charging instruction, that is, an instruction not to restrict vehicle charging.

[0035] Specifically, after the in-vehicle terminal 101 receives the charging status change instruction remotely sent by the back-end management platform, it parses the charging status change instruction to obtain the corresponding CAN message, that is, the charging status change message, and sends the charging status change message to the CAN (Controller Area Network) bus of the in-vehicle terminal 101. The charging status change message is forwarded to the vehicle controller 103 through the in-vehicle gateway 102.

[0036] After receiving the charging status change message, the vehicle controller 103, on the one hand, changes the vehicle charging status according to the charging status change message, such as changing the vehicle charging status to "locked charging status" or "free charging status"; on the other hand, it determines the charging status message according to the charging status change message and sends the charging status message to the battery pack management system 104 connected through CAN. The battery pack management system 104 performs corresponding charging operations according to the received charging status message. Among them, the charging operations include a stop charging operation and a resume charging operation.

[0037] The vehicle control device provided by the present invention sends a charging status change instruction to the in-vehicle terminal when the vehicle service expires or is renewed, and the in-vehicle terminal, in-vehicle gateway, vehicle controller, and battery pack management system process the charging status change instruction to restrict or not restrict vehicle charging to achieve the purpose of restricting the travel of vehicles with expired services. Compared with the rough methods of using physical vehicle locking or remote power locking, it can reserve sufficient processing time for vehicle users to handle vehicle service term matters, provides a safe, friendly vehicle control method that can avoid safety accidents caused by violent vehicle locking, and at the same time improves the experience of vehicle users using vehicles and vehicle managers managing vehicles.

[0038] Based on the above embodiments, as an alternative embodiment, performing a charging operation according to the charging status message includes: Receiving the charging status message sent by the vehicle controller via the CAN bus according to the message sending period; Based on the charging status message, determining a restricted charging status; Based on the restricted charging status, performing the charging operation.

[0039] Specifically, after receiving and processing a charging status change message, the vehicle controller sends the obtained charging status message via the CAN bus according to the message sending period, and the battery pack management system receives the charging status message according to the message sending period.

[0040] The battery pack management system further uses the received charging status message to determine whether the restricted charging status is "restricted" or "not restricted", and performs different charging operations according to the different restricted charging statuses. When it is determined that the restricted charging status is "restricted", a charging operation of stopping charging is performed; when it is determined that the restricted charging status is "not restricted", a charging operation of resuming charging is performed.

[0041] The vehicle control device provided by the present invention receives the charging status message sent by the vehicle controller by the battery pack management system according to a period, then determines the current restricted charging status and performs the corresponding charging operation, so as to restrict or not restrict the vehicle charging to achieve the purpose of restricting the travel of vehicles with expired services, and realize a safe and friendly vehicle control method.

[0042] Figure 2 is the second structural schematic diagram of the vehicle control device provided by the present invention, as Figure 2 shown, the vehicle control device further includes: a human-machine interface (HMI) 201 connected to the in-vehicle terminal 101 through the in-vehicle gateway 102.

[0043] The human-machine interface 201 is configured to receive the charging status change message sent by the in-vehicle terminal 101 through the in-vehicle gateway 102 according to the message sending period; and prompt charging status information on the human-machine interface based on the charging status change message.

[0044] Specifically, after the in-vehicle terminal 101 determines and outputs a charging status change message according to a charging status change instruction remotely issued by the background management platform, it is sent to the human-machine interface 201 through the in-vehicle gateway 102 according to the message sending period, and the human-machine interface 201 receives the charging status change message according to the message sending period.

[0045] The human - machine interaction system 201 further reads the received charging status change message. After reading the charging status change message, it determines whether the vehicle charging status is "locked charging status" or "free charging status", and prompts the charging status information on the human - machine interaction interface according to the different reading results.

[0046] In the case where it is determined that the vehicle charging status is "locked charging status", the charging status information prompted on the human - machine interaction interface can be "The contract has expired, the vehicle has locked charging, please renew the fee in time", etc.; in the case where it is determined that the vehicle charging status is "free charging status", the charging status information prompted on the human - machine interaction interface can be "The contract has been renewed, the vehicle has unlocked charging, have a nice use", etc.

[0047] The vehicle control device provided by the present invention receives the charging status change message sent by the on - vehicle terminal by the human - machine interaction system at a period, and prompts the charging status information on the human - machine interaction interface according to the difference of the charging status change message, timely reminding the vehicle user to handle the matter of the vehicle service expiration, improving the vehicle use experience of the vehicle user, and realizing a safe and friendly vehicle control method.

[0048] Based on the above - mentioned embodiment, as an optional embodiment, the determining the charging status change message according to the charging status change instruction includes: Performing authentication and verification on the charging status change instruction; In the case where the authentication and verification passes, parsing the charging status change instruction to obtain the charging status change message; In the case where the authentication and verification fails, discarding the charging status change instruction.

[0049] Specifically, after the vehicle terminal receives the charging status change instruction sent by the background management platform, it first performs authentication and verification on the charging status change instruction to ensure that the source of the charging status change instruction is legal, safe and applicable to the in - vehicle communication protocol.

[0050] In the case where the authentication and verification passes, the vehicle terminal further parses the charging status change instruction, and determines the charging status change message sent to the vehicle controller and / or the human - machine interaction system according to the charging status change instruction. In the case where the authentication and verification fails, the charging status change instruction is discarded to avoid the normal operation of the vehicle control device being affected by illegal and unsafe charging status change instructions.

[0051] The vehicle control device provided by the present invention performs authentication and verification on the received charging status change instruction to ensure information security, and realizes a safe, friendly and reliable vehicle control method.

[0052] Based on the above embodiments, as an alternative embodiment, the charging status change instruction is a lock charging instruction or an unlock charging instruction; When the charging status change instruction is a lock charging instruction, the charging operation is to stop charging; When the charging status change instruction is an unlock charging instruction, the charging operation is to resume charging.

[0053] Optionally, when the charging status change instruction is a lock charging instruction, the charging status change message is a change lock charging message, and the charging status message is a restricted charging message.

[0054] Optionally, when the charging status change instruction is a lock charging instruction, the restricted charging status is "restricted".

[0055] Optionally, when the charging status change instruction is an unlock charging instruction, the charging status change message is a change unlock charging message, and the charging status message is an unrestricted charging message.

[0056] Optionally, when the charging status change instruction is an unlock charging instruction, the restricted charging status is "unrestricted".

[0057] Figure 3 is a schematic flow diagram of remote lock charging provided by the present invention. As Figure 3 shown, when the back-end management platform TSP detects that the vehicle service has expired, it sends a lock charging instruction to the in-vehicle terminal TBOX. The in-vehicle terminal TBOX receives the lock charging instruction, performs authentication and verification on the lock charging instruction. When the authentication and verification pass, it parses the lock charging instruction to obtain a change lock charging message, and sends the change lock charging message to the vehicle controller VCU and the human-machine interaction system HMI through the in-vehicle gateway GW according to the message sending period.

[0058] The vehicle controller VCU receives and processes the change lock charging message to obtain a restricted charging message, changes the vehicle charging status to "locked charging status", and sends the restricted charging message to the battery pack management system BMS according to the message sending period. The battery pack management system BMS receives the restricted charging message according to the message sending period, determines the restricted charging status as "restricted" based on the restricted charging message, and performs the charging operation of stopping charging.

[0059] The human-machine interaction system HMI receives and processes the change lock charging message according to the message sending period, reads the message to determine that the vehicle charging status is "locked charging status", and prompts the charging status information of "the contract has expired, the vehicle has locked charging, please renew the fee in time" on the human-machine interaction interface.

[0060] Figure 4It is a schematic flowchart of remote unlocking and charging provided by the present invention. As Figure 4 shown, when the background management platform TSP detects the renewal of vehicle services, it sends an unlocking and charging instruction to the in-vehicle terminal TBOX.

[0061] The in-vehicle terminal TBOX receives the unlocking and charging instruction, authenticates and verifies the unlocking and charging instruction. When the authentication and verification are passed, it parses the unlocking and charging instruction to obtain a changed unlocking and charging message, and sends the changed unlocking and charging message to the vehicle control unit VCU and the human-machine interaction system HMI through the in-vehicle gateway GW according to the message sending period.

[0062] The vehicle control unit VCU receives and processes the changed unlocking and charging message to obtain an unrestricted charging message, changes the vehicle charging status to "free charging status", and sends the unrestricted charging message to the battery pack management system BMS according to the message sending period. The battery pack management system BMS receives the unrestricted charging message according to the message sending period, determines the restricted charging status as "unrestricted" based on the unrestricted charging message, and performs a charging operation to resume charging.

[0063] The human-machine interaction system HMI receives and processes the changed unlocking and charging message according to the message sending period, reads the message to determine that the vehicle charging status is "free charging status", and prompts the charging status information of "the contract has been renewed, the vehicle has been unlocked for charging, enjoy your use" on the human-machine interaction interface.

[0064] The vehicle control device provided by the present invention sends a charging status change instruction to the in-vehicle terminal when the vehicle service expires or is renewed, and the in-vehicle terminal, in-vehicle gateway, vehicle control unit and battery pack management system process the charging status change instruction to restrict or unrestrict vehicle charging to achieve the purpose of restricting the travel of vehicles with expired services. Compared with the rough methods of using physical locking or remotely locking the power, it can reserve sufficient processing time and timely remind vehicle users to handle vehicle service term matters, providing a safe, friendly vehicle control method that can avoid safety accidents caused by violent locking, and at the same time improving the experience of vehicle users using vehicles and vehicle managers managing vehicles.

[0065] Based on the above embodiment, as an optional embodiment, the charging status change instruction is sent by the background management platform to the vehicle terminal when the vehicle terminal is in an online state.

[0066] Specifically, when the background management platform remotely sends a charging status change command such as a lock charging command or an unlock charging command to the vehicle terminal, it will first detect whether the vehicle terminal is in an online state. If the vehicle terminal is in an online state, the charging status change command will be directly sent to the vehicle terminal. That is, the charging status change command is sent by the background management platform to the vehicle terminal when the vehicle terminal is in an online state.

[0067] Based on the above embodiment, as an alternative embodiment, the vehicle terminal is further configured to receive a text message wake-up message or a ringing wake-up message sent by the background management platform and adjust from an offline state to the online state.

[0068] Specifically, if the background management platform detects that the vehicle terminal is in an offline state, it will wake up the vehicle terminal by using text message wake-up or ringing wake-up, that is, send a text message wake-up message or a ringing wake-up message to the vehicle terminal. The vehicle terminal receives and responds to the text message wake-up message or the ringing wake-up message and adjusts its own offline state to an online state.

[0069] After the background management platform detects that the vehicle terminal is in an online state, it will remotely send a charging status change command such as a lock charging command or an unlock charging command to the vehicle terminal.

[0070] Based on the above embodiment, as an alternative embodiment, in the case where the vehicle terminal fails to adjust from an offline state to the online state, the charging status change command is cached by the background management platform.

[0071] Specifically, when the background management platform wakes up the vehicle terminal by using text message wake-up or ringing wake-up, it may fail for some reasons, which means that the vehicle terminal also fails to adjust from an offline state to the online state. At this time, the background management platform cannot detect that the vehicle terminal is in an online state and cannot send a charging status change command. Then, the background management platform will cache the charging status change command until it detects again whether the vehicle terminal is in an online state after the cache time has passed, and send the charging status change command when the vehicle terminal is in an online state.

[0072] Optionally, the cache time for the background management platform to cache the charging status change command is preset by the vehicle user or the vehicle manager.

[0073] Optionally, the cache time for the background management platform to cache the charging status change command is determined according to the vehicle's current remaining power and the average power consumption rate over a period of time, for example, determined according to the quotient of the current remaining power divided by the average power consumption rate.

[0074] The vehicle control device provided by the present invention can improve the success rate of vehicle control and enhance the user experience of vehicle control by waking up in-vehicle terminals that are not in an online state through methods such as SMS wake-up or ringtone wake-up, and caching charging status change instructions when the in-vehicle terminals are not in an online state.

[0075] Figure 5 is a schematic structural diagram of the vehicle provided by the present invention, as Figure 5 shown, the vehicle includes the vehicle control device 501 provided in any of the above embodiments.

[0076] The vehicle provided by the present invention sends a charging status change instruction to the in-vehicle terminal when the vehicle service expires or is renewed, and the in-vehicle terminal, vehicle gateway, vehicle controller, and battery pack management system process the charging status change instruction to restrict or not restrict vehicle charging to achieve the purpose of restricting the travel of vehicles with expired services. Compared with the rough practices of using physical locking or remotely locking the power, it can reserve sufficient processing time for vehicle users to handle vehicle service term matters, providing a safe, friendly vehicle control method that can avoid safety accidents caused by violent locking, and at the same time enhancing the experience of vehicle users using the vehicle and vehicle managers managing the vehicle.

[0077] Figure 6 is a schematic flow diagram of the vehicle control method provided by the present invention, as Figure 6 shown, the vehicle control method is implemented based on the vehicle control device provided in any of the above embodiments, and the vehicle control method is applied to a background management platform, including but not limited to step 601.

[0078] Step 601: Send a charging status change instruction to the in-vehicle terminal.

[0079] The charging status change instruction is used to instruct the in-vehicle terminal to determine a charging status change message; the charging status change message is used to instruct the vehicle controller to change the vehicle charging status and determine a charging status message; the charging status message is used to instruct the battery pack management system to perform a charging operation.

[0080] It should be noted that the vehicle control method provided in this embodiment corresponds to the vehicle control device described in any of the above embodiments during specific implementation, and details are not elaborated in this embodiment.

[0081] The vehicle control method provided by the present invention sends a charging status change instruction to the on-vehicle terminal when the vehicle service expires or is renewed, and the on-vehicle terminal, the vehicle gateway, the vehicle controller, and the battery pack management system process the charging status change instruction to limit or not limit vehicle charging to achieve the purpose of restricting the travel of vehicles with expired services. Compared with the rough practices of using physical vehicle locking or remotely locking the power, it can reserve sufficient processing time for vehicle users to handle vehicle service term matters, providing a safe, friendly vehicle control method that can avoid safety accidents caused by violent vehicle locking, and at the same time enhancing the experience of vehicle users using the vehicle and vehicle managers managing the vehicle.

[0082] As an alternative embodiment, the vehicle control method further includes receiving control result information returned by the on-vehicle terminal after sending the status change instruction to the on-vehicle terminal.

[0083] Specifically, after the battery pack management system successfully executes a charging operation of stopping charging or resuming charging, the on-vehicle terminal will return control success control result information to the background management platform; within a preset duration after the on-vehicle terminal receives the charging status change instruction, if the battery pack management system fails to successfully execute the charging operation, or if the authentication and verification of the charging status change instruction by the on-vehicle terminal fails, the on-vehicle terminal will return control failure control result information to the background management platform.

[0084] By having the on-vehicle terminal feedback the result information of vehicle control to the background management platform, vehicle managers can intuitively learn about the vehicle control situation and provide a reference for subsequent vehicle management.
